Fimer PVS980-58 - DC Voltage Based Derating

Technical data 97
 DC voltage based derating
The available output power of the inverter depends on both the input DC voltage and the
ambient temperature. The illustration shows this relation (for elevations below 1000 m).
The behavior of the inverter corresponds to the actual PV panel behavior at high
temperatures and ensures optimal performance of the whole PV plant.
The minimum operational DC voltage varies based on the inverter AC voltage:
• PVS980-58-1818kVA-I: 850 V DC
• PVS980-58-1909kVA-J: 893 V DC
• PVS980-58-2000kVA-K: 935 V DC
• PVS980-58-2091kVA-L: 978 V DC
